To aJ/Z 14171/0712, 7i umg/f concern:

Be itknown that I, EDWARD KNEEZELL, a citizen of the United States,residing at El Faso, in the county of El Paso and State of Texas, haveinvented certain new and useful Improvements in Tobacco-Pipes; and I. dohereby declare the following to be afull, clear, and exact descriptionof the invention, such as will enable others skilled in the art to whichit appertains to make and use the same.

My invention relates to tobacco-pipes, and has in view the promotion ofa cool, sweet, and sanitary smoke. j

Broadly, my invention ,consists in inaugurating a series of supplementalducts or conduits in the wall of the pipe-bowl at substantially rightangles to the main duct, which runs from the bowl through the stem tothev mouth. By this means the smoke is caused to travel a greaterdistance than usual, and in doing so it becomes cool and sweet andprevents saliva from entering the lire-bowl. I also provide meansadjacent said supplemental ducts for receiving and holding a filter ornicotinabsorber and means whereby both themain and supplemental ducts orconduits may be easily and quickly drained and. cleaned.

In further and specific explanation of the construction and operation ofparts I make repeated reference to the accompanying drawings, in which'-Figure l is a vertical section through the bowl with the stem brokenaway. Fig. 2 is a similar view of a slightly-modiiiedform. Fig. 3 is asimilar view of a second slight modification. Fig. 4 is a similar viewof a third slight modification. Fig. 5 is a section on line 5 5 ofFig. 1. Fig. 6 isa section on line 6 6 of Fig. 2.' Fig. 7 is a sectionon line 7 7 of Fig. 3. Fig. 8 is a section on line 8 8 of Fig. 4.

Fig. 9 is a detail view, on an enlarged scale, of-

the lower portion of the tube shown in Fig. 3.

Referring to the several figures, A represents the bowl of the pipe, thewall ofwhich is widened at A and B represents the stem leading at rightangles from the bowl A.

C is .the main smoke-conduit, leading from bowl A through stem B.

D D are the supplemental conduits arranged in the widened wall A of thebowl A at substantially right angles to the main conl mental conduit D,arranged at right angles thereto.

d is an enlargement in conduit D adjacent conduit C and is designed tohold a filter or nicotin-absorber, which may be quickly inserted orwithdrawn through the removable plug al', screwed into the lowerextension of conduit D.

E is a wall separating conduits D and D which forces the smoke to ascendconduit D and pass over the top of wall E, which is cut ol" below thetop of the bowl, leaving an opening e between the topof wall E and theremovable plug e for the smoke to passinto the supplemental conduit D.Conduit D is arranged diverging slightly from conduit D as it continuesdownward to open into the main conduit C.

d is a removable plug arranged in the lower extension of conduit D',similar in construction to plug d', and is designed to allow thesalivaor moisture which collects at the juncture of conduits O and D to bewithdrawn.

Referring to the slightly-modied form shown in Fig. 2, the supplementalconduits D D are shown parallel with one another, and theseparating-wall E is considerably narrower than in Fig. 1, necessitatingonly a single plug d3 at the base of the supplemental conduits forcleaning and draining purposes instead of two. Removable plug e issubstantially the same as in Fig. 1, and the opening c is also used.

In the modified form shown in Fig. 3 a single opening is bored from thebase of the pipe up. through the widened portion A of the wall of bowl Aand extending to within .a short space of the top thereof. Into thisopening, `which is at right angles to the m ain conduit C, is adapted tobe inserted a hollow tube F, closed at both ends and having a centrallongitudinal partition f extending nearly to the top thereof, anopeningj being lower ends with alined openings f2 through its shell,adapted when the tube is inserted in the bore of the pipe to registerwith the main conduits C, as shown in Fig. 3. The lower 9, illustratingclearly the small eye f3 on the base of the tube to facilitate theremoval thereof from the pipe after unscrewing the plus ft left. y TubeF is also provided adjacent its ico portion of tube F is shown in'detailin Fig. 105

Fig. 4 shows a very slight modilication of 11o the form shown in Fig. 3,the opening for the reception of tube F being boredrfrom the top of thewidened wall A and extending just below the main conduit C. Theregistering-openings f2 are as in Fig. 3; but instead of the small eyef3 at the base of the tube in Figf I provide a small recess or opening f5 in the top ofthe tube, in which any suitable instrument may be hookedto remove the tube for raining and cleaning. Plug f4 is screwed in thetop of the pipe in this form instead of at the base.

Having thus fully described my invention, what I claim is- 1.' In apipe, the combination of the bowl thereof, the wall of which is extendedlaterally terminating in a stem and provided with an upwardly-extendingpassage and a downwardly-extending passage, and passages in the stem andbowl portion connecting with said passages respectively, saidfirst-named passages being enlarged at their upper and lower ends andcommunicating with holes bored into the top and bottom of said bowlrespectively, and screw-threaded plugs having their interiors bored outscrewed into said holes, substantially as described.

2. A pipe, comprising a bowl and a stem therefor, said stem having apassage therethrough and said bowl having one wall thereof extendingrearwardly, a vertical passage in said rear wall, a passage connectingsaid vertical passage with the cavity in the pipe-y bowl, an inclinedpassage connected to the passage in the pipe-stem and communicating withsaid iirst-named vertical passage, said pipe having holesbored thereintoat the ends of said upright passages, and screw-threaded plugs engagingsaid holes, said plugs being hollowed out to form cups, and saidvertical passage being provided with an enlargement near its lower end,substantially as described.

In testimony whereof I affix my signature in presence of two witnesses.
